rockclimbing in Bolivia with a safe tour operator

Alexander von Ungern lists here, for each year, some of the climbs that were special to him.


Our Son Max is born in November 2022, and we spend less time in the mountains or climbing long steep faces, and climb more at crags, improving our sport climbing, trad climbing in Cadarese IT and dry tooling in Naz. There are still a few memorable ascents for this year: 

cerro Saturno, 21.7, 5000m high, with my step daugther, my fiancee and my 8 months old Son Max! before heading down into the Yungas cloud forest, during which the mules abandonned us. We hiked 2 days (instead of initially planned 3, with a water bottle, 2 goretex jacket, a back back for the baby and a machete in the jungle)

and then within a week, I have 3 consecutive opportunities, which belong to the "harder" multi pitch rock climbs I have done:

Métal Hurlant, 9.9, el Dorado, Grimsel Pass, CH, 15 pitches 6b (6a+ obl.), partly trad, with Birte

Le premier matin du monde, FR, Perron de Vallorcine, 14.9.23, 7a+, 11 pichtes, mostly trad, Gael Mauron (on his 40th Birthday!) & Alexander

voie Loretan, CH, Waldeckspitze Nord, Gastlosen, 17.9.23, 7a+, 5 pitches, Oliver & Alexander

Ice climbing in Norway, 22.12.23 - 1.124, with a grand mother baby sitting Max, while me and my fiancée, climbing 10 different routes (mostly WI5), adding to 23 pitches in the Rjukan Valley. I will especially remember "Verdens Ende", "Sabotörfossen", Trapfossen" and "Fossekjeringa"


Wadi Rum, JO, 16-27.04, trad climbing trip on desert sandstone. We climbed around 70 pitches, on the best-rated routes the region has to offer, the sandstone was better than expected, and the belay stations were less sketchy than expected. It was quite warm in the desert, and probably the best climbing trip I had so far!

Ikarus and Genius, CH, Dômes du Slot (VS), 2 10 pitches routes, trad, 6a + and 6b, with long alpine approaches.

Acotango (6050m) and Parinacota (6330m) Volcanoes, BO, 23 & 25.7, with a 5 months pregnant Fiona, and a future Baby !

Gorges du Verdon, FR, 26.9 - 4.10, multi pitch climbing in the gorges du Verdon, every day, except for one ! Among the very nice and memorable routes are Pâte D'amande, on which we almost got benighted, and "les fils de l'haltères et du Pan", as pretty much every pitch was excellent !

Gastlosen, CH, préalpes fribourgeoises, 25 & 28.02.21, traverse of the central and northern parts of the Gastlosen. Snow was present on the approach, but the rock was dry, and the weather abnormally warm.

Motörhead, CH, el dorado Grimselpass, 20.06.21, a classic 16 pitch route (max 6b) , mostly trad protected. On the way down, Fiona and Alex found a Ibex skull which is now in the living room.
